The First Windows 11 Update Makes AMD CPU Performance Even Worse

Oct. 18, 2021 / Updated by Bessie Shaw to News

Since the official release of Windows 11 on October 5, 2021, a great number of Windows users have encountered two issues affecting the performance of AMD processors. The issues attracted the attention of people from all over the world, as one of them has terribly caused a performance decrease of 10-15%. Things got even worse after the first Windows 11 update has rolled out.

It is discovered that one of the issues can cause L3 cache latency to increase dramatically. The higher the latency is, the worse the performance will be. So as the the latency becomes higher after the first cumulative update to Windows 11 went out, the performance gets worse, slowing down the performance by up to 15% in certain games.

The second bug is related to AMD's preferred core technology, negatively influencing the fastest core on a processor. According to AMD, this bug badly affects the performance on CPU-reliant tasks.

Concerning the first bug, TechPowerUp says that "in our own testing, a Ryzen 7 2700X "Pinnacle Ridge" processor, which typically posts an L3 cache latency of 10 ns, was tested to show a latency of 17 ns," and "this was made much worse with the October 12 "patch Tuesday" update, driving up the latency to 31.9 ns."

However, you don’t need to worry too much as the fixes for the issues are expected to come later this month.

In addition, since the Windows 11 just went live, previous drivers on devices may be incompatible with some games. You may need to update the graphics driver to improve the performance and compatibility. To achieve this, Driver Talent is a good choice.
